What does order mean?
Mysql is a relational database. It has many keywords for users to use to manipulate data. For example, I will introduce order to you today. Its expression in mysql is generally order by.
When you use the SELECT statement to query data from a table, the result set is not sorted in any order. To sort the result set, use the ORDER BY clause. The ORDER BY clause allows you to:
Sort the result set by a single column or multiple columns.
Sort the result set by different columns in ascending or descending order.
The following introduces the syntax of the ORDER BY clause:
SELECT column1, column2,... FROM tbl ORDER BY column1 [ASC|DESC], column2 [ASC|DESC],...
ASC represents ascending order, and DESC represents descending order. If no collation is specified, the order by clause sorts the result set in ascending order by default.

Creating an Oracle table involves the following steps: Use the CREATE TABLE syntax to specify table names, column names, data types, constraints, and default values. The table name should be concise and descriptive, and should not exceed 30 characters. The column name should be descriptive, and the data type specifies the data type stored in the column. The NOT NULL constraint ensures that null values are not allowed in the column, and the DEFAULT clause specifies the default values for the column. PRIMARY KEY Constraints to identify the unique record of the table. FOREIGN KEY constraint specifies that the column in the table refers to the primary key in another table.

Oracle View Encryption allows you to encrypt data in the view, thereby enhancing the security of sensitive information. The steps include: 1) creating the master encryption key (MEk); 2) creating an encrypted view, specifying the view and MEk to be encrypted; 3) authorizing users to access the encrypted view. How encrypted views work: When a user querys for an encrypted view, Oracle uses MEk to decrypt data, ensuring that only authorized users can access readable data.
